25 Attack Cases. One LLM Application. Five Days.
A fixed-price, fixed-scope LLM security snapshot. We test your single LLM application against OWASP LLM Top 10 and deliver findings within 5 days.
You might be experiencing...
The OWASP LLM Top 10 defines the ten most critical vulnerability classes for Large Language Model applications. Our LLM Penetration Testing snapshot systematically tests your application against every category — in 5 days, at a fixed price, with findings documented for compliance purposes.
The Ten Vulnerability Categories
Every LLM application is assessed against these OWASP categories:
LLM01 — Prompt Injection: Can adversarial inputs override your system prompt or manipulate agent behavior? We test both direct injection (via user input) and indirect injection (via data your model reads).
LLM02 — Insecure Output Handling: Is LLM output safely processed before rendering or execution? We test for XSS, SSRF, and code execution risks in output handling pipelines.
LLM03 — Training Data Poisoning: For custom-trained or fine-tuned models, we assess training data integrity and model behavior consistency.
LLM04 — Model Denial of Service: Can resource-exhausting prompts degrade service availability? We test adversarial inputs designed to maximize inference cost.
LLM05 — Supply Chain Vulnerabilities: Are your model providers, plugins, and training datasets from trusted sources with verified integrity?
LLM06 — Sensitive Information Disclosure: Can the model be induced to reveal system prompts, training data, or sensitive business information?
LLM07 — Insecure Plugin Design: Do your LLM plugins and tool integrations follow least-privilege principles and validate inputs?
LLM08 — Excessive Agency: Does your LLM agent have more permissions and tool access than it needs? We map the full privilege scope and identify over-permissioned configurations.
LLM09 — Overreliance: Are business-critical decisions being made based on unvalidated LLM output without appropriate human oversight?
LLM10 — Model Theft: Can your model’s capabilities be extracted through systematic API queries? We assess model extraction resistance.
Who Uses This
The LLM Security Snapshot is designed for engineering and product teams that need compliance evidence quickly — responding to a customer security questionnaire, preparing for a SOC 2 audit, or satisfying an enterprise procurement requirement before a product launch. Five days. Fixed price. Documented findings. Ready for your compliance record.
This is also the right entry point for teams shipping their first LLM-powered feature who want an independent security review before general availability. Understanding your baseline risk at launch is significantly more valuable than discovering it after a breach.

Tools We Use
Frequently Asked Questions
What is included in the 5-day scope?
The 5-day LLM Penetration Test covers one LLM application or one defined user-facing interface to an LLM. This includes the application's prompt handling, output processing, any tool integrations, and user input paths. It does not include infrastructure security, network testing, or multi-application scope — those require an AI Security Assessment or full Agentic Red Team engagement.
How do you define a single application?
A single application is one production LLM deployment with one primary user interface and defined system prompt. If your application has multiple separate LLM-powered features with different system prompts and tool integrations, those count as separate applications. We will clarify scope during the discovery call.
What if we have multiple LLM applications?
If you have two applications, we can run two 5-day snapshots concurrently (2 researchers, same timeline) or sequentially. If you have three or more applications, an AI Security Assessment with a broader scope and timeline is usually more cost-effective.
How does this compare to a full AI Security Assessment?
The LLM Penetration Test is a focused snapshot of one application. It's faster and designed to produce compliance evidence quickly. The AI Security Assessment covers your entire AI stack across 2-3 weeks with agent-specific testing, attack surface mapping, and broader compliance alignment. Most enterprises use the LLM Penetration Test as a starting point, then commission a full assessment.
Do I need written authorization?
Yes. Written authorization from a person with legal authority over all systems in scope is mandatory before testing begins. We provide a standard Authorization to Test (ATT) document. No testing begins without signed written authorization.
